' BINDER.

To all whom t may concern.'

Be it-known that I, WALTER M. A. GALE, a resident of the city of Toronto, in the county of York, Province ofV Ontario, Canada, a subject of the King of Great Britain, have invented certain new and used ful Improvements in Binders, of which the following is a specilication.

This invention relates to improvements 1n binders used in ling loose leaf forms, and

my object is to devise a binder which will be very simple and cheap to manufacture and which will be very efficient in operation.

The invention is illustrated in the accompanying` drawings in which- Fig. 1 is a longitudinal. view 0f part of a binder, the upper clamping member being shown in section;

Fig. 2 a detail showing a slight modilication of the device;

Fig. 3v a plan view of one of the locking members; and

-Fig. 4 a View similar to Fig.V 1 showing. a modiication of the lockvreleasing means.

Fig. 5 is a detail top plan view showing the arrangement of the slides and their operating means as shown in Fig. 4.

ln the drawings like numerals of reference indicate corresponding parts in the different figures.

1 is the bottom clamping member, which in practice will be bound as an integral part of the base or bach of the binder. To this member 1 are secured the bindino posts 2 in any suitable manner. 3 is t e upper clamping member having the usual holes therethrough to enable it to slide on the posts 2. This upper member 3 will, as; usual, preferably be bound with and form an integral part of the cover of the binder.

This upper member will be formed as a flat hollow tube. Within each end of the upper member 3 is a locking lever 4 having ka hole 5 therein towards one end adapted for the passage of the posts 2, the hole 5, however, being of very slightly greater diameter than the posts 2 and lying in alinement with the holes in the members 3. The edges of the hole 5, however, will preferably be rounded oil. The sides 6 of the other end of each lever 4 are bent downwardly to form supports on which the levers are adapted to rock. The center 7 of the end is left extending substantially in the plane ASpecification of Letters Patent. Y PgpiiggmQ-@d Apii8, 1922 y Application filed February 12, 1921. Serial No. 444,468. i f.

ofl thelever and normally extends into open ing 8in the upper-surfaceof thefupper member3;

To retain the locking leverswithin the upper clamping membenl form slots 9 between the holes 5 and the'ends of the levers, and through these slotsare passed pins l() permanently secured inside the member .3. The ends ofy the locking levers will Enormallytend to drop Atowards the bottom ofn the member 3 at an angle tothe latter, but the engagement of the sides of the post in the holes 5 will besuch thatthe ends of the` levers will not be allowed to quite touch the bottom ofthe lmember 3 so that the levers will exercise a cramping action against the sides ofthe posts to prevent theV raising of the member 3 on 'the posts 2. VPressure on the ends 7 through the openings -8 will raiseth'e levers to a position parallel with the top of the member 3,' when the member 3 may be easily lifted f on the posts 2.

lf desired, the ends v7 of the locking levers` may beA bent down 'sli`ghtly as' shown in Fig. 2, and headed pins 11 extending through; they upper side of the` member* 3 secured thereto. n f

ln Fig. 4 I showfa modificationof the means for releasing the lockingI levers 4.' A sliding plate 12 is arranged at each side of a stem 13 extending up through the upper surface of the member 3 and provided with a suitable head by which it may be rotated. This stem has a cam-shaped end having its greatest width normally lying Atransversely of the member 3. When the stem v13 is rotated a quarter circle, the plates 12 are pushed forward to raise the lowered ends of the levers 4, the plates 12 being provided with tapered ends to assist their entry beneath the ends of the levers. Pins 15 are secured to the upper surface of the sliding plates to keep the plates in their proper position. A bent spring 16 passes around the pins 15 nearest the stem 13, which tends to return the plates to their normal position.

With reference to my preferred construction as shown in Figs. 1, 2 and3, it will be noted that the same parts may be used for posts any distance apart and that the locking levers' may be inserted in the member 3 with their parts 6 on which-they rock l0- cated between the two posts 2 instead of liio between the ends of the member 3 and the posts. y

It will also be seen that With my preferred construction' shownA in Fig. 1 that only the posts 2 project above thefupper surface of the member 3. This is of great importance when the binder is being bound with canvas yor leather, as 1s usually done, asv

anyV projections interfere With. thevcovering of the parts, and Vit is not even neces-V sary to out avvay thel canvas or leather over the openings 8; as there is enough give in this material'to allow ofthe release ofthe l. ln a binder, the combination of a base; posts secured to the base; a tubular clamp-- ing member having holes therein 'for the passage of said posts; pins in said' clamping member lockingy levers Within' saidmember each lever having an opening. therethrough through which. one of saidl pins loosely passes andan opening in alinement with the holes in the elampingjmembenthe lastl mentioned opening' being of slightly greaterdiameter than the: posts,a-downvvardV extensionV 'at' one endyof each4 of said levers on which thelevers may rock to engage the sides Voit' the posts with a cramping action; and meansl for vrocking said levers to disengage them from the posts.
